I'm a weak Exorcist, and the Yanderes Around Me Aren't Human

Kaito Reizen is the shame of Japan's most powerful exorcist clan.His spells are weak, his attitude is soft, and he keeps making friends with the ghosts he's supposed to destroy.He lives alone in his aunt's old house in Kurami, away from his family, with exactly one roommate — an ancient, silver-haired Umbral named Shizuka who he cannot exorcise, cannot reason with, and absolutely cannot get rid of.She's been attached to him since childhood.She's terrifyingly strong.She is in love with him in a way that keeps him up at night.Between university, a father who gave up on him, a sister who hates him with alarming intensity, and a growing number of very dangerous supernatural women who have decided he belongs to them, Kaito's life is complicated.The ghosts don't make it simpler
